JSON Transformation Error

Hi all. I am getting data from a Sharepoint Online List. It has several fields and one is in JSON format. When I transform it I can expand it. I click to expand, then again and expand to new rows. I get three columns named label, reason code, and notes from the example below. 


{"items":[{"label":"A-1","reasonCode":"CLAIM OK-NO ISSUES","notes":"but return in SC for non repair"}]}


When I close and apply I get the following error. "OLE DB or ODBC error: [Expression.Error] The parameter is expected to be of type Text.Text or Binary.Type.


The columns come up in ABC123 format when I expand. I even tried converting them to text. No luck. Thoughts on what could be causing the issue?

Re: JSON Transformation Error


Is there any possibility that you can export the JSON field to a flat  JSON file so that I can test? Or you can use JSON connector in Power BI Desktop to connect to the exported JSON file and check if the error still occurs.
